WOOL-BURRING MACHINE.

To all whom t may concern Be it known that I, WILLIAM CUNDELL, ofPaterson, in the county of Passaic and State of New Jersey, haveinvented new and useful Improvements in Machines for'Cleaning Wool andother Fibrous Substances, and that the following is a full, clear, and'exact description of the principle or Y' character which distinguishesthem from all other things before known and of the manner of making,constructing, and using the same, reference being had to theaccompanying drawings, making part of this specification, in which- Y lFigure l isa longitudinal elevation of the machine; Fig. 2, a frontelevation; Fig. 3, a section through the cleaning and the shear- -ingcylinders; and Fig. 4, separate views of the rings of teeth and theplane rings inter-l posed in forming the cleaning cylinder. V The sameletters indicate -like parts in all u .the figures.

A machine for cleaning` wool has heretofore been made with the cleaningcylinder composed of metal rings with the teeth formed by `cutting intotheir periphery, so that the points of the teeth shall not projectbeyond the general periphery of the cylinder thus formed, the spacesbetween the several rings and the spaces cut out to form the teeth beingso small as not to admit bursl or other coarse impurities; but inthisthe space cut out to form ,the teeth was made much larger withinthat at the periphery, the defeet of which is that a large quantity offibers accumulate within this space than can be drawn out and thus themachine chokes. The different rings were so arranged as to have thespaces between the teeth of one ring correspond with the middle of theteeth of the next, which I have found prevents the free reception of thefibers. The object of the first part of my invention is to avoid thesedefects which I do by making the spaces or slots cut out between theteeth no wider at bottom than at the periphery which efl'ectuallyprevents choking, and delivers the fibers to the card with facility; andI facilitate the reception of the fibers by arranging the teeth oftheseveral rings in a line whether parallel with the axis of the cylinderor diagonal thereto. In the machine referred to, the cleaning cylinderwas so combined with a carding engine as to take thev place of thetumbler and have the carding cylinder to take the fibers directly fromexperiment to be defective; this I have much improved by introducing thecleaning cylinder between the feed rollers and the tumbler that takesthe fibers from the cleaning cylinder to transfer them to the 'cardingcylinder this constitutes the second-part of my invention. And linallyinthe machine referredto the burs,' motes,`&c.', were sheared or cleanedoff by means of what istermed the cleaning roller whichfconsists oflongituf dinal blades or strips projecting from the surface of a4cylinder in lines parallelwith the axis. This I deem to be defectivebecause they act byintermission and entirely the cleaning cylinder whichI havefound byy Vvl acrossthe whole length yof the cylinder aty once. Myimprovements in'this part of the 1 machine` consist in placing theseguardsw cleaners or shears diagonally, on the surface of a cylinder, orin curved lines so as to act continuously on the cleaning cylinder; and

also in making'them of sheet metal bent in.,V the form ofsemi-cylindersy inverted andsol.-` dered to the surface of'a hollowcylinder so thatftheir edges shall come together to form the blades,cleaners, or shears, which are thus braced in oppositeydirections.' f

In the accompanying drawings (A)v represents the carding 'cylinder of acardingen gine, (B) the tumbler, and (C) the stripper, all constructed'andarrangedfin the usual manner of carding'engines; The feeding rollersand aprons areremovedsufhicientlyfrom the tumbler to admit between themthe cleaning cylinder (D) vwhich receives the fibers from the feed apron'and rollers and transfers them to the tumbler to i be carded in theusual manner; but before passing to the tumbler the fibers are actedupon and stripped of the motes, burs, and other impurities by the rotaryshear guard (E) which strips off all the impurities that project abovethe surface of the cleaning cylinder, as indicated by arrows, and the`teeth on the tumbler ypass the` teeth of the cleaning cylinder, (movingin the samedirection) with suficient'velocity to take'the Y fibers fromthe teeth of the cleaning cylin-' der and transfer them to the cardinthe usual manner. Y

The vcleaning cylinder fis composed of a series of metal rings (e) ofteeth slipped and secured on an included cylinder (f) with rings (z')made ot flattened wire int-en.

posed. The teeth are formed on the rings (c) by cutting yin slotstangential toa circle of' about two-thirds the diameter of the pe'-riphery of the rings, theV sides of each-slot@ being parallel, or nearlyso, which `prevents the fibers and other impurities from accum-v ulatinginsuch `quantities wit-hin ,the slots Soas to choke them up, but notsufficiently wide to-admit motes, burs. &c. And the series of rings (e)should-be so arranged as to have the slots in a continuous line eitherparallel with the axis or diagonal thereto. The slots shouldl also bemade of greater depth than the projection ofthe teeth beyond theperiphery ofthe intermediate rings Vso that as t-he points ofthe teethwear they canbe' sharpened and the same length of tooth retained bygrinding or otherwise reducing the diameter of the rings of teeth andthe spacing or intermediate rings. The usual thickness of these rings isabout one twenty-sixth Vof an inch so as to have about thirteen of eachkind to an inch; they are secured `and held on the included cylinder `bybeingclamped between a permanent lanch (g) Aon one end of the cylinder,and a movable one on the other end secured by a key or screw in mannerwell known to machinists. Y

The stock of the rotatingshear guardv is a hollow cylinder made of sheetmetal with headsto form the connect-ion with the shaft; and to theperiphery of this cylinder are secured t-he guards or shears (n) whichare made of sheet metal semi-cylindrical, with the-convex part solderedor otherwise secured to the cylinder with the edges pro- "jecting atequal distances from the periphery. These are arranged around thecylinder with the edges placed against and soldered to each other, twoedges thus brought and secured together forming one shear or guard.`Theyare arranged as represented in Fig. 2, each inclining in oppositedirections :trom` the middle of the length of the cylinder so as to actdiagonally from this point in either direction and thus clear offV'the'1notes, burs, &c., more regularly and effectually than whenplacedparallel with the' axis. Or, Iplace them either in a zig-zag line,as represented in Fig. 5, or in curved( lines as in Fig. 6, these twoacting on the same `principle as the first example, and

therefore introduced simply to show that theV vsame principle can bevariously applied.` i.

As the carding part of this machine is constructedand operates 1n mannersimilar to the common carding engine 1t 1s deemed `unnecessary to give adescription ot it.

l/Vhat I claim as my invention and desire;

`tosecure'by-l'netters Patent, isy y 1. Making the spaces or slotsbetween the,

teeth offequal width, from the point to the bottom of the teeth, whenthis `is applied to teeth the peripheries of which are` concentric,

so that when the rings of teeth are all put together the outer portionof the space shall be of the same width as the space within, and

the surface of each tooth from point to back `shall be a segment of acylinder and concentric, substantially as described. y

2. I claim making Vshears or guards for clearing oli' the impurities, ofsheet metal bent in semi-cylindrical forms and connected together by theedges and with the included cylinder by the `convex surface,substantially as described.
